Robust Detail E-FC-14

Robust Detail E-FC-14 is an under screed acoustic insulation system for precast plank floors. E-FC-14 provides 3 Code for Sustainable Homes Credits upon registration.

It consists of Isorubber Base resilient acoustic insulation below a sand & cement screed with Isoedge 6/260 perimeter separation strip and a Metal Frame ceiling supported on Isosonic Ceiling Cleats or an Isosonic Ceiling treatment.

System Summary

Robust Detail E-FC-14 is an acoustic solution for precast plank floors. This system provides a minimum 5dB improvement the requirements of Approved Document Part E. When registered with Robust Details Ltd the requirement for on-site sound testing is removed and 3 Code for Sustainable Homes / BREEAM / Home Quality Mark credits are automatically awarded.

Benefits

  • Exceeds Building Regulation requirements by minimum of 5dB.
  • No need for sound testing if registered with Robust Details Ltd.
  • Provides 3 CSH/BREEAM/HQM credits upon registration.
  • System uses Isorubber Base to reduce noise transfer, this is a tough, resilient acoustic mat that can withstand the rigours of the screeding process.
  • Purpose made Isoedge strip and Isosonic Ceiling Strip are used to eliminate flanking sound transfer.
  • No long term / short term deformation of acoustic layer.
  • Suitable for use with Under Floor Heating

Components & Specifications

Acoustic Performance

As a Robust Detail that provides 3 Code for Sustainable Homes Credits the E-FC-14 system must always achieve individual site test values of:
Airborne Sound – not less than 50db (Dntw + Ctr)
Impact Sound – not greater than 57db(Lntw)
This exceeds the Building Regulation (Approved Document Part E) requirements by 5dB in both cases.

Isorubber Base

Roll Size  6mm x 1m x 10m
Roll Weight  37kg (14 Rolls per pallet)
Density  635kg/m³
Isorubber Base is a 6mm thick acoustic insulation and vibration-reducing mat that can be laid beneath a screed or timber floating floor to reduce impact sound and vibration transmission to assist in sound proofing applications. A very durable product with a density of approximately 635Kg/m3, Isorubber Base does not suffer from any dete...

IsoEdge

Products Include:
Isoedge 6/75
Isoedge 6/260
Isoedge Ceiling Strip
Isoedge Stop End
Isoedge Door Stop
The Isoedge range of perimeter isolation and acoustic formwork are very important components of our acoustic systems that help to reduce flanking sound transmission. They can also be used to provide an expansion joint for timber floating floors. Installation is simple with features such as adhesive backing strip, break-out joints, and...

About System

The E-FC-14 system was the first under screed system to gain 3 Code for Sustainable Homes Credits status. Its consistent high performance and compatibility with all masonry flanking external wall types, including aircrete blocks (450- 800Kg/m3) make it the obvious pre-cast plank system to choose when looking for 3 Code for Sustainable Homes Credits.

The E-FC-14 system consists of 6mm Isorubber Base fitted below a minimum 65mm sand & cement screed with Isoedge 6/260 separating the screed from the wall. The structural floor must be a minimum 150mm precast plank with a minimum mass of 300Kg/m2 per unit area. This system can be used with all masonry external flanking wall constructions (450 – 800Kg/m3, 1350 – 1600Kg/m3 & 1850 – 2300Kg/m3). A metal frame ceiling supported by Isosonic Cleats with a minimum void of 150mm or an Isosonic Ceiling is also required. Both ceiling details are under drawn with a layer of gypsum based board (minimum 10Kg/m2) and have a minimum of 50mm mineral wool in the ceiling void.

During the extensive site testing carried out for Robust Detail classification all 30 of the impact and airborne tests had to achieve a minimum 5dB improvement over regulation requirements to gain this status. Due to this excellent performance record any site that registers the E-FC-14 system with Robust Details is automatically awarded 3 Code for Sustainable Homes Credits.

As part of the E-FC-14 registration Thermal Economics provide site training to Site Managers and Screeders by experienced industry professionals who will instruct on installation procedures and answer any questions regarding your specific project.

The E-FC-14 system can also be, and is frequently, used in non Robust Detail specifications, subject to pre-completion testing.
